Abstract
Description
Dem Ausgang A des Verstärkers der Stereoanlage sind fünf Breitbandlautsprecher 1, 2, 3, 4 und 5 in Parallelschaltung zugeordnet. Dem Ausgang B des Verstärkers sind fünf weitere Lautsprecher 6, 7, 8, 9 und 10 in Parallelschaltung zugeordnet. The output A of the amplifier of the stereo system are five broadband loudspeakers 1, 2, 3, 4 and 5 assigned in parallel. The output B of the amplifier are five more speakers 6, 7, 8, 9 and 10 in Parallel connection assigned.
Die Lautsprecher 1 bis 5 haben eine Grundtonresonanzfrequenz von 20,60,100,140 und 180 Hz. Die Lautsprecher 6 bis 10 haben eine Grundtonresonanzfrequenz von 40, 80, 120, 160 und 200 Hz. Jeweils zwei Lautsprecher mit einer benachbarten Grundtonresonanzfrequenz sind unterschiedlichen Ausgängen A oder B des Verstärkers zugeordnet. Diese Anordnung ist dann vorteilhaft, wenn die den Ausgängen A und B zugeordneten Lautsprecher sehr weit voneinander entfernt angeordnet werden, um den Stereoeffekt zu erzielen. Loudspeakers 1 to 5 have a fundamental resonance frequency of 20, 60, 100, 140 and 180 Hz. The speakers 6 to 10 have a fundamental resonance frequency of 40, 80, 120, 160 and 200 Hz. Two loudspeakers each with an adjacent one Fundamental resonance frequency are different outputs A or B of the amplifier assigned. This arrangement is advantageous when the outputs A and B assigned loudspeakers can be arranged very far apart to the To achieve a stereo effect.
Diese Anordnung ist aber keineswegs zwingend, denn es können die Lautsprecher 1 bis 5 auch den Lautsprechern 6 bis 10 parallel vor- oder nachgeschaltet sein, da im Tieftonbereich das menschliche Ohr ohnehin nicht zu unterscheiden vermag, aus welcher Richtung die Töne anlaufen. Das heißt, die Lautsprecher 1 bis 5 können auch Grundtonresonanzfrequenzen im Abstand von 20 Hz aufweisen und ebenso die Lautsprecher 6 bis 10. However, this arrangement is by no means mandatory, because the Loudspeakers 1 to 5 are also connected in parallel upstream or downstream of loudspeakers 6 to 10 because the human ear cannot distinguish in the low frequency range anyway, from which direction the tones start. That is, speakers 1 to 5 can also have fundamental resonance frequencies at a distance of 20 Hz and so do the loudspeakers 6 to 10.
Jedem der Lautsprecher 1 bis 10 ist ein Kondensator 11 bis 20 in Reihe vor- bzw. nachgelagert. Die Kondensatoren 11 bis 20 verringern die Grundtonresonanz der zugeordneten Lautsprechermembranen und verhindern gleichzeitig das sonst so typische Flattern. Each of the speakers 1 to 10 has a capacitor 11 to 20 in Upstream or downstream row. The capacitors 11 to 20 reduce the fundamental resonance of the assigned loudspeaker membranes and at the same time prevent this otherwise typical flutter.
Als Folge der Grundtonresonanzdämpfung kann jeder der Lautsprecher, wie für die Lautsprecher 1 bis 5 (F i g. 3) gezeigt, eine trichterförmige Membrane 21 aufweisen, welche von der Rückseite her betrachtet erhaben ist. Die Membranen sind jeweils an einer Montageplatte 30, 31 befestigt, wobei sie Bohrungen 33 durchgreifen. Der Durchmesser der Bohrungen 33 ist, wie aus F i g. 2 zu erkennen ist, dem Membrane-Durchmesser der einzelnen Lautsprecher 1 bis 10 angepaßt. Die Montageplatte ist nicht größer als unbedingt für die Halterung der einzelnen Lautsprecher erforderlich, da eine zusätzliche Boxenresonanz unerwünscht ist. As a result of the fundamental resonance damping, each of the loudspeakers, as shown for speakers 1 to 5 (Fig. 3), a funnel-shaped membrane 21 have, which is raised when viewed from the rear. The membranes are each attached to a mounting plate 30, 31, and they reach through holes 33. The diameter of the bores 33 is, as shown in FIG. 2 can be seen, the membrane diameter the individual speakers 1 to 10 adapted. The mounting plate is no larger as absolutely necessary for the mounting of the individual loudspeakers, as a additional speaker resonance is undesirable.
Die Membranen strahlen einerseits nach vorn in Richtung der Pfeile 22 Schallwellen ab, gleichzeitig aber auch nach hinten in Richtung der Pfeile 23, so daß ein Raumtoneffekt erhalten wird. Ein Gehäuse für die einzelnen Lautsprecher ist bei dieser Ausbildung nicht erforderlich, so daß auch nicht der übliche Dröhneffekt wie bei der Verwenndung von Boxen auftritt. On the one hand, the membranes radiate forward in the direction of the arrows 22 sound waves from, but at the same time also backwards in the direction of arrows 23, so that a room sound effect is obtained. A housing for the individual loudspeakers is not required in this training, so that the usual booming effect is not as occurs when using boxes.
Die Lautsprecheranlage gibt eine sehr klangvolle Tieftonabstrahlung. Besondere Lautsprecher für den mittleren und oberen Frequenzbereich sind nicht erforderlich, da die vorgesehenen Tieftonlautsprecher mit ihren Oberschwingungen diese Frequenzbereiche vollkommen mit ausfüllen. The loudspeaker system emits a very sonorous low-frequency sound. Special loudspeakers for the middle and upper frequency range are not required, because the intended woofers with their harmonics cover these frequency ranges complete with.
Lautsprechermembranen haben mit zunehmender Größe einen größeren Schallwiderstand bzw. Dämpfung. Bei der erfindungsgemäßen Ausbildung ist es möglich, dies zu berücksichtigen. Loudspeaker cones have a larger size the larger they are Sound resistance or attenuation. In the training according to the invention, it is possible take this into account.
